Nero
"Depends. Are you going to be my nurse if I can't go on?" he smirked once more as he took to the air, taking care of one Swarm before stopping in his tracks, "I said that out loud, didn't I?" His momentary fade of concentration allowed one of the Swarms to grab him from behind, cutting both of his shoulders with something, although Nero didn't exactly know what. Nor did it matter. Flipping the Swarm over his body, he made him cut him a little deeper due to the sudden change in pressure, both he was still able to handle it.
After the Swarm regained composure, the blade of Nero's sword was already pointed at him. And Nero did not hesitate. "Unravel." And with a single swipe, the blade unfolded, cutting Swarm's head into two, before Nero kicked him into the fire. The cut part of the head didn't even get the chance to multiply as Nero swung his sword and launched the part into the fire as well. "Homerun," he muttered, as he made a few swipes in the air with his prolonged blade.
